Which aspect does NOT influence population dynamics?

Population dynamics refers to the changes in population size and composition over time, influenced by various factors such as birth rates, death rates, immigration, and emigration. Birth rates, death rates, and immigration all play direct roles in determining how a population grows or shrinks.

Temperature fluctuations, while they can influence the habitat and overall ecosystem stability, do not directly dictate population dynamics in the same way the other factors do. Temperature may affect reproduction rates or survival indirectly by changing the environment or resources available to a species, but it is not a primary factor in the demographic processes that govern population numbers. Thus, it does not influence population dynamics as directly as the other factors listed.
